Well technically it's not a unicycle as it has 3 wheels (originally had two but that design was unstable when the front wheel extends)

It's an interesting idea though the uno - I can see some people buying it for a cool factor more than anything else. As has been said, it's going to be expensive until they sell to the masses and until they are made cheaper, they won't sell to the masses.I'm more interested in BPGs DVT shredder...

Back onto unicycles, the Segway self balancing unicycle looks more interesting. As a unicyclist, I would be interested to see if you can hop and do tricks on one like you can do on a BC wheel (basically a BMX wheel with two plates stuck on it to stand on - no seat).

No, the picture is a similar vehicle called the Uno. It is a transforming 3 wheeled motorbike which can self balance on the back wheel (two wheels now due to stability issues when extending the front wheel when there was only one wheel on the back).

That Ryno one looks interesting too.

Cool, you just need an Arduino set up to play "Transformers, Robots in disguise .." every time you go from two wheels to three or three wheels to two
